Nested ``switch`` structures are difficult to understand because you can easily confuse the ``when`` blocks of an inner ``switch`` as belonging to an outer statement. Therefore nested ``switch`` statements should be avoided.

Specifically, you should structure your code to avoid the need for nested ``switch`` statements, but if you cannot, then consider moving the inner ``switch`` to another function.

== Noncompliant Code Example

|
|
public void foo(Integer i, Integer j) {
|
|
switch on i {
|
|
when 1 {System.debug(' 1'); }
|
|
when 2 { System.debug(' 2'); }
|
|
when -3 {
|
|
switch on j { // Noncompliant
|
|
when 1 {System.debug(' 3');}
|
|
when else {System.debug(' 4');}
|
|
}
|
|
}

}
